I can't get it, its a 4 x 4 box each with a number with a pattern that i can't crack, there is a missing number, whats the pattern and the number? it looks something like this:

7 4 2 6
8 2 4 3
5 3 5 7
2 ? 6 8

I think it might be 2. The numbers seem to come in pairs:
There are two 8s, two 7s, two 6s, two 5s, two 4s, two 3s, and three 2s. With another 2, you'd get two pairs of 2s. Hope this helps.
